Duplicate screen from ipad to ipad via cable
 

Hi folks, I have two Ipad 9.7 2018. The first one is fixed in an awkward position due to camera usage. I would like to use the second Ipad to see whats on the screen of the first one. This must be via a cable connection as Wi-Fi is not possible (it is important that there is no latency between the 2 Ipads).

I have been using a PC monitor with the HDMI adaptor but the monitor takes up too much space. So dump the monitor and use a 2nd ipad instead :-)

Can anyone tell me how to do this??
